Definition
The slope of a line is a ratio that represents the change in y over the change in x.
Description
Understanding the relationship between ratios and slope is essential for interpreting graphs and solving problems in algebra and geometry. The slope is a measure of how steep a line is, calculated as the ratio of the vertical change to the horizontal change between two points.
For example, if a line rises 2 units for every 3 units it runs horizontally, the slope is 2/3. This concept is crucial for understanding linear relationships and analyzing data in various fields.
Teacher's Script: "If you have two points on a line, (1, 2) and (4, 5), the slope is calculated as (5 - 2)/(4 - 1) = 3/3 = 1. This tells you the line rises 1 unit for every 1 unit it runs."
